Liver hormone secrets revealed: new study could reshape diabetes drugs

This study looks at how the hormone glucagon works with insulin in the liver to manage blood sugar. Researchers want to understand glucagon's multiple, sometimes opposite, roles to create better diabetes medicines. Forty healthy adults aged 18-45 will have two 5-hour sessions where they receive either glucagon or a saltwater solution while their blood sugar is kept steady. The goal is to learn how these hormones improve the liver's response to insulin.
